Referringl nowVt'o the drawings by nul*merals of -reference 1 designates Lthe main frame plement such asl a harvester'or the like, and

.fl thev auiiliar'y carrier or-"fi'aniefor the 'engine'2,liere shown 'to lbe of the ordinary 'vertical-type having a base mounted upon the "carrier'l fby bdlts 3 passing through the :.base andth'r'ough :thboss'es 4 on the'carrier iframe.

The auxiliary carrier 'is preferably of *'Askeleton construction. coinprising diverrging .side 'ra-ils Vl12, 'having vbearings comprising main bearingY parts 5 atvtheir split 'ends incation of the bearings to the tubular drags of the i1n-v i los Y adjustable in the main frame to adapt the Vcarrier to frames of dierent heights. yThe tubular drags or couplingmembers comprise bearings for a transmission shaft 8 which is connected with the engine on the carrier and with the operatingmechanism on the harvester. I

- machine is Working.

In Figure VI I have shown the brackets 9 as comprising front and back plates adapted to lie'against opposite faces of a cross bar of the main frame and provided with a plurality of openings 10 to receive the bolts 11 and 12 whereby the plates may be attached to the cross bar in adjustedpositions. At the apex of the frame I have shown a tubular bearing 13 to receivethe pintle or shaft 14 of a caster wheel 15 adapted for vertical adjustment by means of the collar 16 and set screw 16 whereby the auxiliary frame may be raised and lowered to conform yto the height of the main frame and maintain its longitudinal plane when the carrier is first applied to the main frame and when the height of the main frame is adjusted to conform to the height of grain in which the The shaft 8 is connected with the operating mechanism of the harvester, preferably by achain running over a sprocket wheel 17 on the coupling shaft and over a sprocket wheel 19 on the drive shaft 2O of the harvesterV or other implement, the shaft 20 being provided with a beveled gear 21 which meshes withr a pinion 22 on the counter-shaft 23 from which gpower is usually communicated to the sev-r eral parts ofthe harvester; Any suitable means may be employed for communicating motion from the engine to the shaft 8but I have here shown the engine shaft 24 as provided with a sprocketQ Vin line with a sprocket wheel 26 on shaft 8, the sprocket wheels'25 and 26 being connected by a chain 27. The sprocket wheels 17 and 26 may be moved longitudinally on the shaft to permit removal of the shaft from its bearings, but normally serve to retainthe shaft in place.

The main implement selected for the purpose of illustration is shown as a harvester VVVprovidedwith a tying mechanism shaft 28,

an elevator driving shaft 29 and a lateral conveyor shaft 30, these being provided with sprockets 317 32 and 33 respectively and having motion communicated thereto by the endless sprocket chain 34,.which receives' its motion from the sprocket wheel35 lon the counter-shaft 23. j c

It will be assumed that the harvester is to be conductedthrough a field by horse or pling to the ,harvester parts so that such parts are driven to perform their functions but do not necessitate an additional load on the motive power that would be induced were the harvester parts driven from the ground wheels.

It isj apparent that by removably connecting the` auxiliary carrier with the implement, a single framey and engine may be used witha numbernof different implement-s and that when the engine is not required for yuse with any implement, the carrier may be disconnected and supplied with the auxiliary axle 36 and ground wheels 37 and 38whereby the engine may be conducted fromplace to place for general use, such as wood sawing, silo filling, etc. The

auxiliary support is preferably of the form shown, constituting the arched axle 36 connected with the frame through the bearings 5 and 6 and having end spindles 39 and 40 on which the ground wheels are supported,

the axle being braced vby the rod 41.

, Vhen the engine is to be employed for general use a belt 42 may be run over' a pulley 43 on the engine shaft to transmit power as desired. i

Thus it will be seen that the power unit to secure by LettersPatentis:

1. Incombination, a. vehiclev comprising operating mechanism and having combination bearing and coupling members for fa transmission shaft and an auxiliary carrier, a transmission shaft rotatable infsaid bearing member, a carrier connected with saidy couplings, an engine mounted on the carrier, and means connecting the transmission shaft with the operating mechanism and with the engine.

2.7In. combination, a vehicle comprising operating mechanism'and having combina- ,tioncoupling and bearingmembers rigidly supported thereon for vertical' adjustment relative thereto, a shaft journaled in said bearings, an engine carrier connected to said bearings, an engine` mounted on the carrier, means directly connecting the shaft with the operating mechanism and means connecting the shaft with the engine.Y Y

3. In combination, a vehicle frame, a pair `of spaced bracketsl carried thereby, bearin ,sleeves in saidbrackets, a shaft'v journale in said bearing sleeves, an engine carrier comprising' a rigid frame, and means connecting said frame at spaced points to said bearing sleeves.

4. In combination, a vehicle frame, a pair of brackets vertically adjustable on the frame, a shaft journaled on said brackets, an engine carrier connected to said frame through said shaft, and a caster Wheel adjustably supporting the rear end of said I engine carrier.

5. In combination, a vehicle, brackets on the vehicle, coupling members on the brackets having interior bearings, a shaft journaled in said bearings, a carrier having pivotal mounting on the coupling members, an engine on the carrier, means connecting the shaft With the engine, and operating mechanism on the vehicle connected with said shaft.

6. In combination With aV vehicle, operating mechanism carried thereby, brackets on the vehicle comprising aligning coupling members having interior bearings, a shaft removably and rotatably mounted in the interior bearings, a carrierv having bearings pivotally mounted on theV coupling members of the bracket, an engine on said carrier, and means connecting said shaft with the engine and With said operating mechanism.

7. In combination, a vehicle, comprising brackets and horizontal bearings, a carrier comprising a fra-me having horizontal bearings at its free ends engaged by the horizontal bearings on the vehicle, and a vertical bearing at the opposite end, a shaft removably mounted in the horizontal bearings coupling the carrier to the vehicle, and acaster Wheel having a standard mounted in said vertical bearing..

8. In combination, a harvester, vertically adjustable spaced brackets carried by said harvester, an engine support coupled to said brackets, and an adjustable caster Wheel supporting the free end of said carrier.
